Two important use cases for Data Science skill assessment test

#1 Identifying job-fit candidates based on job roles

You can build customized data science skill assessments for any given job role. Using this capability, you can choose questions from different skill types, including functional, technical, and soft skills. For example, with our customized data scientist coding assessment, you can assess candidates' understanding of Data Extraction and Mining, Numerical Ability, Interactive Reporting, Python Coding, and Machine Learning and hire the best individuals for the job.

#2 Skill-gap analysis of your employees

iMocha allows you to trace employees' skill competency through data science training assessments. It determines the current skill level and identifies the areas for growth. Using this feature, you can measure employees' progress from their existing knowledge base to gained knowledge. For example, you can use our data science training assessments to identify an engineer's knowledge about Sampling Distribution, SQLite Coding, Quantitative Aptitude, and other skills and perform a skill gap analysis.

Test Creation Process

We provide various types of data scientist hiring tests to help you evaluate candidates' specific skills. These questions are created by Subject Matter Experts (SMEs) based on their knowledge and expertise. For example, only Data Science specialists will develop questions about Data Manipulation using R or Machine Learning based on easy, medium, and hard difficulty levels.

You can - choose which questions to include in the Data Scientist coding test or ask us to create personalized assessments according to your requirements.
